How does stomach create noises?
In: Biology
Squeeze a sponge. Forcing air through water makes noise.
You’re basically a long tube with muscles that squeeze that tube. Sometimes when it’s trying to push the water forward the air bubbles backwards.
The air is both air you swallow, and gases produced by the fermentation of what’s in your gut via the action of bacteria and whatnot.
So it works the same way air bubbles in the pipes make your house grumble.
